allowed to type in a Y or a N. I specifically have a problem with
using the PropertyDescriptorCollection. I get the following error:

I am writing a customized DataGrid control which will allow the user to only
select an entire row (and not a cell inside the row). So I want to add
readonly columns to the datagrid. To achieve this, instead of using a
"DataGridTextBoxColumn" inside the datagrid I want the control to use a
"DataGridTextBoxColumn" that has a disabled "Edit" method. Therefor I have
created my own version of a "DataGridTextBoxColumn" class called...

I use DatagridTableStyle to display data from table
WF_Carrier_FreightChart. USers than can add/delete/edit rows in the
Datagrid.
Since the Datagrid's datasource "dCarrierFreight" is just a copy/view of the
table (dataset dFreight.tables(0) ), I need to update the original table to
reflect multiple changes in the Datagrid.
Your help is greatly appreciated.

For example:

a way to do it anyway.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
